To all whom it may concern:

Be it known that I, BA-x'ma R. HUNTER, a citizen. of the United States, resid' -j at Kings ntain, in the count of Cleve and a and State of North Carolina, ve invented new and useful Im rovements in Lubricators of which the fo owing is a specification.

invention relates toan im rovem'ent The in oiling-devices and is particular y directed to a construction whereby'a vehicle wheel may be automatically and continuouslypiled to be applied to the hub during the travel of the vehicle.

The main object of the present invention is the provision of an oiling device ada ted a vehicle w eel and normall prevented from delivering oil to the spin e, the construction including a manually adjustable arm adapted. on each revolution of the wheel to so 0 crate the oilshowmg parts of the trip lever and support.

' from of a device.

. restricted opening 5.

ing device as to permit the 'elivery therepredetermined quantity of oil to the spindle.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings,

vation of a wheel hub and axle showing the application thereto of my improved oiling Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is an elevation partly in section of the oilin device. Fig. 4 is a vertical section of the oi ing device. Fig. 5 is an elevation of the trip lever and support. Fig. 6 is a perspective View, partly broken away,

Referring particularly to the accompanying drawings, my improved oilin device is designed for use in connection wit 1 a vehicle wheel 1, the hub 2 of which is provided with a boxing 3 which is of usual construction exce t that it is formed with a relatively offset cy indrical chamber 4 in communication with the interior of the boxing through a The wall forming the chamber 4 is set into the material of the hub, and said chamber, which extends practically throughout the length of the boxing, may be.

hereinafter termed the oil chamber. The boxing is.(lcsignod to fit a spindle 6 carried by the axle 7 in the usual manner, any suitable securing means, as 8, serving to secure the wheel in place. An oil cup 9 is arranged to deliver the lubricant to the oil chamber 4 said cup comprising a hollow cylindrica body 10and a depending hollow stem 11 in communication with the body. The relatively lower end of the stem is threaded, as at 12, and said stem is arranged to be inserted throu h an opening 13 formed in the hub, the three ed end of the stem engaging a threaded o ening in the wall of the oil chamber 4. The body 10 is formed in the top with a filling opening 14 normally closed by a cap 15, and the stem adjacent its juncture wit the bed is provided with a screw bolt 16 ar-' ranged or movement transverse the opening in the stem whereby to adjust the size-of said 0 and thereby the flow of oi'l throug the same.

The side Wall of, the body, thereof, is provided with an 17, the lane of which is preferably at an angle,to t e axis of the body to preventthe escape of the oil in the operation of the device. The air vent is normally closed by' a valve late 18, which'is pivotally mounted at its Power end, as at 19, on the body and formed at its u per end with a disk head of a size to cover 1: e an ventwhen the plate is in one position. Projecting outwardly from the disk head of the valve plate relatively to the cup is an angle arm 20, the upper portion of which projects in arallel relation to the axis of the oil cup an terminates above the top of the cup, providing what will be hereinafter termed a trip arm 21. A clamp 22 is secured upon the axle adj acent the spindle and is provided with ears I 23 between which is pivotally mounted an upri ht 24. The upright is-preferably divided ongitudinall for adjacent theitop a portion of its length to provide space sec-.

tions 25 between which at the u per end is pivotally mounted a lever 26, hereinafter termed the trip lever. In the lever'adj acent its pivotal connection is formed a series of openings 27, arranged in a circle concentric with the pivot and adapted to be engaged at will by a pin 28 projectmg from a spring arm 29, which at one end, as 30, is secured to the upright, the in passing through an o ening 31 in one of t e sections 25 and eing a aptm to engage any one of the openings 27. 'By this construction the lever 26, may be set at any desired angular relation to the upright 24, for a purpose which will presently appear.

It is to be understood that the clamp is so arranged on the axle thatwhen the tri lever 26 is m normal-positiofl,fthat is'at rig t angles to the-support, the outer or free end of air inlet opening said lever will, in thetravel ofthevehicle, engage the trip arm 21 of the valve plate'at each successive revolution of the wheel. This movement will ventthe oil cup and pen;

mit a quantity of oil, regulated by the olt 16, to pass to the oil chambere and from the latter to the spindle? lhe valve plate is spring pressed in a direction 0 posite that in which it is moved by the tri ever by a leaf It is, of course, understood that as lon as v the vent opening is closed no oil will 0wfrom the oil cup, but when said opening is ex osed b operating the'valve plate, the oil, w' l flow rom the on as long as air is admitted to the body. hereforeiat each revolution of the vehicle wheel the tri arm will act to operate the valve plate an thereby vent the oil cup, thus'deliverin'g to the s indle a definite quantity of oil at each rev' 0 ution of the wheel. v 1

By the adjustment described for the lever 26 the duration of operative eflectofsaid lever may be controlled as desired, as will be apparent- -When it is not desired to automatically deliver the oil to the wheel the operator can simply release the trip lever from the holding means and turn it to the rearward position to or away from tlie'valve cup.

The improvedconstruction provides a'simple device which with the parts in operative position will act .to automatically lubricate a: vehicle Wheel without requiring an {attention on the part of thenperator, such ubricati'on continuing as long as oil remains in'the cup. Having thus described the invention what is claimed as new", is A 1.
